  • Patent number: 7770714
    Abstract: A transfer apparatus includes a first magnetic member placed in a carrier, and a second magnetic member placed in a carrier supporting unit to oppose the first magnetic member from a position below the first magnetic member in the vertical direction, and having the same polarity as that of the first magnetic member. The repulsive force generated between the first and second magnetic members vertically pushes up the carrier, thereby reducing the weight of the carrier supported by the carrier supporting unit.

  • Publication number: 20090308317
    Abstract: The peeling-off of a deposited film caused by a carrier is restrained, and the exchange period of the carrier is prolonged. In a carrier 1 including a slider 7 having a mechanism for conveying a substrate holder 3 that supports a substrate 2, a deposition shield 20a, 20b that can cover the substrate holder 3 and has an opening equivalent to or larger than the substrate 2 on which a film is formed is installed on both surfaces of the substrate holder 3. At this time, the substrate holder 3, supporting claws 4, and fixing parts 6 are arranged so as to be hidden by the deposition shield 20. In a film forming chamber, to form a predetermined film on the substrate 2, the carrier 1 covered by the deposition shield 20 is exposed to a plasma space in the film forming chamber, and the film is formed. The deposition of film onto the substrate holder 3, the supporting claws 4, and the fixing parts 6 that are covered by the deposition shield 20 can be restrained.

  • Patent number: 6202592
    Abstract: A substrate holder for holding a circular substrate in a vertical position during processing of the substrate. The substrate holder is provided with a vertical base plate and three support claws which are mounted on the base plate and which hold the peripheral edge of a substrate. One of the three support claws is a fixed support claw which holds the edge of the substrate at the bottom to support and whose position does not change when the weight of the substrate is supported. The other two support claws are moveable and may be actuated to hold the edge of the substrate at its sides to restrain motion of the substrate. The moveable support claws can be opened and closed for substrate mounting and removal. The two movable support claws are installed on the base plate in a manner so that when the substrate is supported by the fixed support claw they contact the side edge at locations which are higher than the height of the center of the substrate.

  • Patent number: 5976255
    Abstract: A substrate holder to support a substrate in a vertical position in a substrate processing device that performs a process on the substrate, where the process involves forming a plasma in the space around the substrate. The substrate holder includes a base plate and a plurality of supporting claws that are attached to the base plate and arranged so as to come into contact with the outer edge of the substrate and provide vertical support for the substrate. At least one of the plurality of supporting claws is a movable supporting claw that can be brought into contact with and separated from the outer edge of the substrate. When a substrate has been loaded into the holder, the space around the substrate is substantially filled by the base plate or by a member attached to the base plate.
